We demonstrate a high-resolution 0.5 mm isotropic volume rendering dataset created from digital subtraction of 3D TOF and 3D-DANTE prepared FLASH (3D-DASH) black blood images, showing significant improvement in revealing small arteries. In addition, the visualization quality of the MIP images generated from a subtracted dataset is greatly improved in comparisons to its original TOF version.
